Directions

Fit a pie crust into a 9-inch pie dish and arrange sliced apples into crust. Spread cranberries over apples. Whisk sugar, cornstarch, and cinnamon in a small bowl and sprinkle mixture over cranberries. Distribute butter pieces over pie filling. Place remaining crust over filling, crimp both crusts together, and cut several slits into top crust to vent steam.

Bake until pie is browned and fruit filling is bubbling, 45 minutes to 1 hour.
